Naphthalene Superplasticizer imakhala mankhwala a ufa kudzera pa sulfation, hydrolysis, condensation, neutralization, kusefera, ndi kuyanika utsi. Kapangidwe ka naphthalene-based high-efficiency water reducer ndi okhwima, ndipo ntchito ya mankhwala imakhala yokhazikika. Kumbali imodzi, mankhwalawa angagwiritsidwe ntchito mwachindunji mu konkire, ndipo ntchito ya konkire yochepetsera madzi yakhala yodziwika bwino ndi akatswiri. N'zothekanso kufotokozera zotsatira za kusakanikirana kwakukulu kapena kosakwanira pa ntchito ya konkire; Komano, naphthalene superplasticizer ali bwino kusinthika ndi admixtures ena, ndipo angagwiritsidwe ntchito monga zikuchokera composite admixtures, monga kupopera wothandizira, wothandizila madzi, mpweya-entraining madzi reducer, antifreeze, etc., amene angakhale naphthalene ofotokoza ofotokoza. mkulu-mwachangu kuchepetsa othandizira. Wothandizira madzi; Pomaliza, ndizotsika mtengo ndipo zitha kuvomerezedwa ndi gulu la engineering. Choncho, naphthalene-based high-efficiency superplasticizers akhala chinthu chodziwika bwino cha superplasticizers chapamwamba kwambiri m'dziko langa ndipo chakhala chogwiritsidwa ntchito kwambiri.
Ngakhale kuti naphthalene-based high-efficiency water reducer ili ndi ubwino wambiri, imakhalanso ndi zovuta zina, makamaka chifukwa imakhala ndi zotsatira zoipa pa kusungirako pulasitiki konkire. Kuwonongeka kwa nthawi ya konkire pogwiritsa ntchito naphthalene superplasticizer ndikokulirapo kuposa konkire ya Benchmark; ngakhale kuti madzi ochepetsera madzi ndi okwera kwambiri, zimakhala zovuta kukwaniritsa zofunikira za konkire ndi kuchuluka kwa madzi otsika kwambiri, komanso pamtunda wochepa wa madzi-binder Pogwiritsidwa ntchito mu konkire yamphamvu kwambiri, viscosity yake idzakhudzidwa. Konkire ndi yaikulu, yomwe si yabwino kumanga. Pofuna kupititsa patsogolo bwino ntchito ya naphthalene-based high-efficiency water reducer, njira zotsatirazi ziyenera kutsatiridwa: Onjezani zowonjezera zowonjezera (mankhwala) ku naphthalene-based high-efficiency water-reduction kuti muchepetse zofooka zake. Kumbali ina, ma naphthalene superplasticizers amatha kukhathamiritsa posintha magawo a mamolekyulu (kulemera kwa maselo, kugawa kwa maselo, digiri ya sulfonation) kapena kusintha gawo la naphthalene ndi ma monomers ena ogwirizana kuti apange ma copolymers.
